I belive it would be 253 and 1/2 units.

6.5 x 6.5 = 42.25 (Area of one side)

Cube has 6 sides so 42.25 x 6 = 253.5

Suppose y varies directly with x. if y=-3 when x=5 find y when x=-1

Scrat [10]

$\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x

&& y={{ k }}x
\end{array}
\\ \quad \\
\textit{we know that, when}
\begin{cases}
y=-3\\
x=5
\end{cases}\implies y=kx\implies (-3)=k(5)$

solve for "k", to find the "constant of variation",
then plug it back in the y = kx, to get the equation
now
what's is y when x = -1?
well, just plug that in the equation with the found "k" value,
to get "y" :)

What is the value of x in the equation x – y = 30, when y = 15?

slamgirl [31]

Since −y does not contain the variable to solve for, move it to the right side of the equation by adding y to both sides.x=y+30
